what oils are you using with your TT setups
 

Hey guys wondering what oil you all are using with your TT setups. I am running 5W30 but recently my tuner is saying I should bump up to 5W40 as I am having higher oil temperatures. Is this true?

I dunno the answer to your question.. but I run Shell Rotella T6, as advised by my tuner... not suitable for cars with cats though.

I use royal purple hps. Car seems to love it

5W-30 and 5W-40 have the same cold or low end protection, but the 5W-40 has a higher temperature threshold than 5W-30. I just made that switch myself, so far no problems. I am using Motul Ester 5W-40.

I am running 0w-40 Mobile 1 European Blend.. Also interested if this is acceptable or not. In Florida with a 600hp/550tq car.

Rotella T6 :driving:

That Mobil one 0/40 is Factory filled in the GTR.
What is your external oil cooler size; as they’re a must w/TT Z’s

I have used Mobile 1 0-40 in my Z before it was boosted and switched to Rotella T6 after installing my BP kit.

I have used several different brands and they are all good. I started tracking my z so now I run 0w50 Eneos. I have run Mobil 1 and Liqui Moly in 0w40 as well.

My original oil cooler came with my BP kit, so I believe my spacer was 1 qt and the oil cooler eats up a decent amount. I got in a wreck and had to by a new oil cooler and it was a bit bigger and keeps my oil at 170 to 190 at all times.

I think last change I added a 5 qt jug and then the best of 2 extra single qt bottles.

You are good to go...I ran that here in AZ with no issues.

I ran a 40 weight oil in my car over the summer and had zero issues. I like to run 30 in the “cooler” Florida months and 40 from about June to October.

The biggest deal is to get your oil up to operating temp and keep it there. The next is about handling the additional heat from the FI system so that parts don't break down due to lack of lubrication. I just got a report back from Blackstone and it came back with flying colors.

Even with my small oil cooler I rarely see operating temps above 208/210. This time of year in Florida I’ll be lucky to have my oil temp within operating “spec” temps, which I believe starts at 180?? These are not track temps. This is just driving normally around town, getting on it here and there, stop and go traffic etc.

Remember you can add about 10* to 20* based on where the oil temp is taken. My temp here in the winter can get fairly cool...in the 50s and 40s. When cruising on the highway my temp gauge will read 160. You may need to block part of your oil cooler off to get temps to stay up. Under normal conditions mine is always about 200 or 210.

hmmmmm i am trying a 5w40 with my car tuners recommendation...originally my temp was getting to 220 just a trip to a gas station with no boost...we are going to see if this helps the temp come down

What kind of oil cooler are you using?

Which one though? There's more to oil than what temp your gauge ends up showing, or what numbers the bottle shows. I wasn't going to say anything because there are entire websites/forums dedicated to oil, ( http://bobistheoilguy.com ) but the fact that your tuner simply suggested a different weight, and not an actual product, means he doesn't really have any idea what to tell you. Other than, "you'll run hotter, buy bigger numbers". Im not FI yet, but I run Mobile 1 0W-40. You will find that this oil is loved by many folks for scientifically tested reason. I'd say do lots of research, or get advice from someone who actually knows what they are talking about, which is what you are doing here. "Trying 5w40" doesn't sounds like the best approach though.

This and if your plumbing is not right can have a significant impact on cooling or heating things up.

Just an FYI... The "W" does NOT stand for weight. It actually stands for winter. The lower the number, the lower the cold temperature protection.

I run the 0w-50 Eneos in my Supra. Seb changed me over from M1 to that before he tuned it.

I’ve been thinking about fabricating a block off I can slide in for the cooler months. My intercooler is already in front of my oil cooler so it doesn’t have direct exposure. Just a b**** to access lol

LOL, I know exactly what you mean!

Are you guys saying even with a thermostatic plate, oil temps are not warming up in a timely manner? What's going on?

Well I was talking about the oil temp remaining in spec whenever you’re just cruising down the road and occasional mild “spirited” driving. If I got the hammer down the oil temps go up but when the cooler air is steady on it the temps will drop well under that spec temperature. Which I believe is 180 degrees F. But don’t quote me on that just yet.

As long as you stay above 160 you are good to go. A sandwich will help to a degree. I run without one!

Probably because they have the oil temp sensor in the stock location (post cooler) which isnt ideal. I would see 80/100 degree oil temps in cool weather in this location, i switched the sensor pre cooler and saw 170/180 degree temps. This happens because the oil gets overcooled when the plate is closed>limited flow to the cooler and when it mixes with the oil going back to the block you see really cool temps. Anyone else experience this too?

Now the real question is
What brand of gas are you using with your TT setup?

ugh this is the worst part of being in Korea...the gas out here is so unregular that I have to tune at a 91 octane in case a station i go to claiming to have 93 is actually 91....better to be on the safe side than running lower than what i am supposed to

Are you the black Supra that he recently tuned but won't show numbers?

Reviving an old thread....Anyone else have any experience with the Eneos brand? Wish we had a supplier here. I’m currently using the Mobil 1 European blend 0W-40 as well. Heard great things also about Liqui Moly which just recently became available here through a local distributor but comes in at a cost of almost $95.00 for a 5 liter bottle ur could probably get it cheaper through an employee discount @65.00 for a 5liter 0W-40 as well. Trying to figure out if I should make the switch to this or the Eneos. Mobil 1 runs about under $40 for 6 quarts out here.

schaeffer's 5w50 race oil with zinc/phosphorus additives.

remember, you are feeding oil to the engine and turbos.. this car runs hot as is and you want the best protection... when i ran n/a i just had mobil1 5w30 synthetic..
